CRP and soluble E-selectin were increased in patients with microangiopathy, compared with the control subjects ( p<0.01 and p<0.05), whereas von Willebrand factor did not differ between the groups.
Microangiopathy from atherosclerosis or amyloid angiopathy might lead to the formation of these lesions; therefore, there may be associations between CMBs and cardiovascular risk factors, APOE allele status, and brain morphology.
Thrombin-induced platelet P-selectin expression was enhanced, and soluble P-selectin and sCD40L concentrations were increased in patients with microangiopathy compared with the control subjects ( p<0.01 for both) and with patients without microangiopathy ( p<0.05 for P-selectin expression and sP-selectin), whereas all three parameters were similar in patients without microangiopathy and in the control subjects.

NADPH oxidase (p22(phox)) and HO-1 gene expression were probed by RT-PCR using leucocytes from patients with Type 2 diabetes without (n = 19) and with microangiopathy (n = 20) and non-diabetic subjects (n = 17).
However, HO-1 gene expression was significantly (P < 0.05) lower in patients with (0.73 +/- 0.03) and without microangiopathy (0.85 +/- 0.02) compared with control subjects (1.06 +/- 0.03).
In obese subjects, NOS3 4a (P=0.011) had a converse effect to NOS3 894T (P=0.043), and EDN1 8002T (P=0.035) on the prevalence of combined microangiopathy (neuropathy/retinopathy/nephropathy) vs. microangiopathy-negative subjects.
The study indicates association of RAS variants with obesity and nephropathy, and an opposite effect of NOS3 VNTR and NOS3G894T on the occurrence of combined microangiopathy.
The study aim was to investigate NOS3 VNTR, NOS3 G894T, EDN1 C8002T, ACE I/D, AGT M235T and AGTR1A1166C in nonobese and obese T2DM patients, and their interaction with the incidence of microangiopathy.
These were as follows (number of patients in brackets): Aicardi-Goutières syndrome (33), cerebroretinal microangiopathy with calcification and cysts (10), band-like calcification with simplified gyration and polymicrogyria (6), COL4A1-related disease (3), Degos disease (2), Krabbe disease (2), Alexander disease (1), mitochondrial disease (1), and tetrasomy 15 (1).
The GG genotype of the PEMTG774C polymorphism, higher levels of serum homocysteine and lower levels of serum betaine are associated with an increased risk of microangiopathy in patients with diabetes.
Taken together, these results not only identify a genetic cause of a glomerular microangiopathy but also suggest that the phosphatidylinositol cycle, which requires DGKE, is critical to the normal function of podocytes.
